Abstract: An apparatus includes a plurality of components and a plurality of component controllers. Each of the plurality of component controllers is associated with at least one component of the plurality of components. Each component controller is configured to compute a local power budget for the at least one component based, at least in part, on the power differential and the proportion of the total power consumption corresponding to the at least one component. A service processor is configured to determine failure associated with at least one component controller of the plurality of component controllers or the at least one component associated with the at least one component controller. The service processor is configured to in response to a reset threshold not being exceeded, reset the at least one component controller without interrupting operations of any components of the at least one component that have not failed.

Abstract: Component power consumption is collected from each of a plurality of controllers of a node having a plurality of components. The component power consumption is provided to each of the plurality of controllers. A power differential is determined as a difference between a power cap for an apparatus and a total power consumption for the apparatus based, at least in part, on the component power consumption. A proportion of the total power consumption corresponding to the at least one component associated with the at least one component controller is determined. A local power budget is computed for the at least one component based, at least in part, on the power differential and the proportion of the total power consumption corresponding to the at least one component. A failure associated with the at least one component controller or the at least one component is determined.

Abstract: An approach is provided in which a master thermal controller utilizes a primary fan manager to control fans included in a computer system to cool various devices. When the master thermal controller determines that the primary fan manager is unresponsive, the master thermal controller transfers master thermal control to a backup thermal controller. The backup thermal controller creates fan control information based upon sensor information corresponding to the various devices, and sends the fan control information to a backup fan manager. In turn, the backup fan manager adjusts the speed of the fans according to the fan control information.

Abstract: A JTAG bus cross point switching device that is commanded by the same bus which it configures. In a preferred embodiment a JTAG chain includes a cross point switching device that is capable of adding, omitting, or rearranging devices on a JTAG bus. The switching device itself is controlled by commands on the JTAG bus which it configures.
